3-dimensional cone-beam computerized tomographic cephalometric database on jaw dimensions in Chinese

Abstract

Aim: To create the World’s first database on 3-dimensional cephalometrics on jaw sizes in Chinese based on cone-beam computerized tomography (CBCT). Materials and Methods: 40 consecutive CBCT (20 males and 20 females) of a Chinese population of age ranged 21 to 30 were studied and evaluated cephalometric measurements on jaw dimensions. Results: Six cephalometric measurements Cdl-A, Cdr-A, Cdl-Pg, Cdr-Pg, Cdl-Cdr and A-Pg were measured. All except A-Pg were significantly larger in males. Conclusion: The availability of a database in a population allows research and clinical use of cephalometrics and comparisons of various craniofacial dimensions among different populations to the 3-dimensional level.
